Recently, when the on-chain congestion is heavy, I watch the mempool, and it really feels like waiting in line at a busy intersection: you sign and send your transaction, but all you get is a "queue number." Miners/validators will first pick the ones with higher tips, which are more profitable for them, and the rest just keep waiting. You think confirming the transaction is the end, but in reality, it might get stuck, be bumped, or even expire and become invalid, and then you realize that the term "slippage" essentially means the price has moved while you're waiting in line...

These days, someone also compared RWA, US bond yields, and on-chain yield products. Listening to it, I can't help but chuckle a bit: on the surface, it's about interest rates, but underneath, it's often about the liquidity and congestion costs of whether you can smoothly enter and exit the market. Anyway, I no longer chase explanations; I accept randomness: tip appropriately, don't rush in during the busiest times, rushing too fast can also cause you to fall.
